Abstract
Knife arrangement for a granulator for granulating plastic ropes with two draw-in rollers and a cutting rotor (9) cooperating with a counter-knife (2), and a striper (3) facing one of the draw-in rollers (11), whereby counter-knife (2) and striper (3) are mounted on a common support, whereby the striper (3) is arranged adjustably for adjustment of the distance between the striper (3) and the draw-in roller (11), and whereby the striper (3) has a support surface (6) for feeding the plastic ropes (12) to the counter-knife (2) and the cutting rotor (9), and is provided on one side with a striper edge (18) projecting towards the draw-in roller (11), and on its other side with an end edge (7) projecting towards the counter-knife (2), whereby the support (1) has a support surface (4) facing the striper (3), on which the striper (3) rests with a counter surface (5) adapted to the support surface (4), whereby support surface (6) and counter surface (5) approach each other towards the counter-knife (2) in a wedge-shaped manner, such that the end edge (7) is formed cutting edge-like, and the striper (3) together with the support (1) reaches the counter-knife (2) essentially continuously.
